AMERICAN tourist David Wills had been browsing at books on the second floor of a London Waterstones bookshop on Thursday night and did not realise the shop was closing.
By the time he did, it was too late. He was locked inside it.
Not one to be trapped by his circumstances, Mr Wills took to social media to report about his situation about an hour after he was locked in.
He tweeted what happened together with his location, and attached a picture from his Instagram account to his tweet. The picture showed that the bookstore was shuttered.
After another hour had passed, he sent out another tweet, which tagged the Waterstones' official Twitter account.
It said: "Hi @Waterstones I've been locked inside of your Trafalgar Square bookstore for two hours now. Please let me out."
The Independent reported that the Metropolitan Police came to Mr Wills' aid at 11.20pm, about two hours after his first tweet was sent out.
The Metropolitan Police had done so after receiving word about a man trapped at the store, wrote the Independent. It was unclear if they had come to know about it from Mr Wills' tweets, or if they had been alerted by a netizen who came across the tweets.
Just after midnight, the official Waterstones twitter account posted: "We're pleased to announce that David Wills is a free man once more. Thanks for your concern and tweets!"
To close this chapter, Mr Wills' made a final tweet about his bookstore adventure: "I'm free."
